hey rusty...

1) the fan is not hooked up to a hood. i'm using a reflector.

2) i rarely spray anything on them, but occasionally (less than once a week) i spray a weak solution of AN Jumpstart (seaweed extract) while the lights are on.

3) I'm not using any calmag, or any calcium or magnesium supplement. i thought my tap water would be sufficient.

4) my watering schedule has been consistent since they were young. they are exposed to a continuous spray from the aerospring, 24 hrs a day.

5) the roots are offwhite/cream/yellowish. they look extremely healthy, but i wouldn't know for sure since this is my first grow. some of the roots are almost 1/2 inch thick. the 2 plants share a reservoir which is about 12 inches deep, and the reservoir with the nutes is in an adjacent tub underneath, so that the roots are sitting in a very shallow pool of nutes (1/4 inch) at all times.

p.s. i was thinking about using molasses and/or epson salts.

thanks for the input rusty, your experience is much valued. later.
